Title: Improved cryoprotectant solutions
Inventor: FAHY GREGORY M
IPC: A01N37/02
Filed: 1999-09-21
Abstract: Surprising new combinations of previously-known and novel cryoprotectants are provided that yield superior recovery of function and viability of living systems after exposure to and removal from said systems. These and related combinations are useful for cryopreservation by vitrification, freezing, supercooling, freezing point depression, or cold storage. It is disclosed that, contrary to current opinion, ideal solutions for cryopreservation are those that vitrify "poorly" (i.e., at higher rather than at lower concentrations). Contrary to expectation, by using relatively "poor"  vitrifiers, the water content of the solution is reduced at the concentration needed to vitrify, but the water availability within the solution is believed to be paradoxically increased, thereby increasing viability. A novel method for understanding and predicting non-specific cryoprotectant toxicity is provided based on a new definition of cryoprotectant "concentration", which is the number of water molecules per polar group on penetrating cryoprotectants.  Compositions are provided that vitrify at relatively high concentrations, yet surprisingly also devitrify slowly on warming. Databases of novel vitrification/devitrification and toxicity data are provided that allow the ordinary practitioner of the art to select specific solutions or obvious solution variants to meet the user's specific cryopreservation needs.

Title: Wastewater treatment tank with influent gates and pre-react zone with an outwardly flared lower portion
Inventor: LINDBO GLEN D
IPC: B01D21/08
Filed: 1999-09-28
Abstract: A wastewater treatment tank with influent gates (24) and pre-react zone with an outwardly flared lower portion. Influent passes over influent gates (24), which introduce turbulence, causing aeration, and reducing flow velocity. As influent flows out of the influent gate housing (20), flow velocity is further reduced by contact with the surface of the wastewater in the basin and influent flow is directed laterally by an influent gate bottom (30). A pre-react zone director (34) spaced apart from the bottom (42) of the basin encloses the influent gate housing (20) and utilizes an outwardly flared lower portion, or flap (38), to further reduce flow velocity and enhance laminar flow. This results in minimal disturbance of settled sludge blanket, allowing it to act as a natural biological filter, which in turn results in a superior supernatant.

Abstract: A method and system for monitoring out-put power of transceivers in radiocommunication systems are described. By evaluating a statistic associated with pre- and past handoff received signals, information can be gathered regarding the transmit power operating characteristic of various transceivers. For example, by measur-ing the received signal strength of a neighbor-ing base station's control channel prior to hand-off and comparing that with the received signal strength of a traffic channel transmitted by the same base station after handoff, the system can acquire information regarding the power output of a base station transceiver. Over time, the sys-tem can determine whether one or more power settings associated with that transceiver needs ad-justment.

Abstract: In an IP-based cellular telecommunications network, such as for example in a Code Division Multiple Access (CDMA) 2000 cellular telecommunications network, a method, a system and a Packet Data Serving Node (PDSN) for registering a Mobile Node (MN) with the PDSN. Once a Point-to-Point Protocol (PPP) connection is established between the MN and the PDSN, a PPP timer is started, the PPP timer being set to expire after a predetermined period of time. A Mobile Internet Protocol (MIP) registration takes place between the MN and the PDSN. The PDSN detects if the MIP registration is successful and if so, resets the PPP timer to a substantially higher value and the PPP session continues until one of the involved parties terminates it. If the MIP registration is not successful, the PDSN further detects if a new MIP registration request is received before the expiration of the predefined period of time, and if so, the PDSN resets the PPP timer again to the predefined period of time. Otherwise, if a new MIP registration request is not received before the timer expiration, the PDSN terminates the PPP connection. The PDSN comprises the PPP timer, an RP stack for supporting an RP connection, a PPP stack activated for the duration of the PPP connection, and a foreign agent for performing the MIP registration of the MN, which may be implemented using software or hardware modules, or a combination thereof.

Title: Optical filter using a linear variable filter with elliptical beam geometry
Inventor: DUGGAN PHILIP PATRICK
IPC: G02B6/32
Filed: 2002-02-01
Abstract: This invention relates to a new optical geometry for using a linear variable  filter as an optical spectral filter. An elliptical beam geometry with the minor beam axi s oriented along the linearly varying axis of the filter is used. The beam is incident at a slight angle relative to the long axis of the beam. Ultimately this geometry produces a filter which has minimum spectral broadening from both angular and beam extent effects. Furthermore, this geometry results in low back reflectance and higher input beam power damage thresholds. The optical filter includes means for tuning a wavelength  response of the filter. Further, the optical filter can afford Add/Drop functionality by  providing optical circulators at the input and output ports.
